Embodiment 1

[0059] In order to more clearly illustrate the process and advantages of the inventive method in this embodiment, the present invention provides a smoke detection method.

[0060] figure 1 It is a schematic flowchart of a smoke detection method provided by an embodiment of the present invention.

[0061] See figure 1 , The smoke detection method provided by the embodiment of the present invention may include the following steps:

[0062] S11. Obtain the smoke density value of the target environment.

[0063] Specifically, a certain environment is defined as a target environment, and preferably, a kitchen is taken as an example here for description. For example, after detecting smoke in the kitchen, the smoke detection module detects the smoke concentration value in the kitchen. The smoke detection module is preferably the smoke detection system in the NB smoke detector, which is used to detect the smoke concentration value in the kitchen.

[0064] S12: Determine whether the smoke dens...

Embodiment 2

[0082] In order to further explain the technical solution of the present invention, the present invention also provides another embodiment.

[0083] figure 2 This is a schematic flow diagram of another smoke detection method provided by an embodiment of the present invention.

[0084] See figure 2 , Yet another smoke detection method provided by an embodiment of the present invention may include the following steps:

[0085] S201: Detect whether there is a human body in the target environment.

[0086] Still taking the kitchen as an example to detect whether there is a human body in the kitchen, preferably, a human body detection module is used to detect human body information, and a pyroelectric infrared sensor can be used to detect human body information.

[0087] S2011: If no human body is detected in the target environment, obtain a smoke density value in the target environment.

[0088] Specifically, still taking the kitchen as an example, when no human body is detected in the tar...

Embodiment 3

[0110] In order to be compatible with the foregoing method embodiment and further illustrate the technical solution of the present invention, an embodiment of the present invention also provides a smoke detection device.

[0111] image 3 This is a schematic structural diagram of a smoke detection device provided by an embodiment of the present invention.

[0112] See image 3 , The smoke detection device provided by the embodiment of the present invention may include: a smoke detection module 31, a control module 32, a temperature detection module 33, a combustible gas concentration detection module 34, and an alarm module 35;

[0113] The smoke detection module 31 is used to obtain the smoke density value of the target environment, and send the smoke density value to the control module 32;

[0114] The control module 32 is configured to receive and determine whether the smoke density value is greater than the calibrated smoke threshold, and when the smoke density value is greater tha...

Abstract

The invention, which belongs to the technical field of smoke detection, relates to a smoke detection method and device and a detector. After a smoke sensing concentration value of a target environmentis detected to be larger than a calibrated smoke sensing threshold value, whether the target environment temperature value exceeds a temperature threshold value is determined again, so that that a fire phenomenon occurs in the target environment is determined after the temperature value exceeds the temperature threshold value, thereby giving a fire alarm. When the temperature value is lower thanthe temperature threshold value, whether a combustible gas concentration value exceeds a combustible gas concentration threshold value or not is determined, so that the pot overflowing phenomenon is accurately judged; and technical problems that in the prior art, a smoke detector gives an alarm after detecting smoke, kitchen smoke, fire alarm and pot overflowing phenomena cannot be distinguished,and thus potential safety hazards are generated are solved.

Description

Technical field [0001] The invention belongs to the technical field of smoke detection, and specifically relates to a smoke detection method, device and detector. Background technique [0002] Overflowing refers to the phenomenon that the water in the pot boils and overflows from the pot. The phenomenon of pot overflow is very common in the kitchen, especially when boiling soup or porridge. Because it takes a long time, people usually put the pot on the stove directly or leave the kitchen after setting the time, and wait for enough time. Return to the kitchen to check and turn off the fire. Unattended, after the water boils, it is easy to overflow the pot, which will extinguish the fire on the gas stove. Once the fire on the gas stove is extinguished but the gas is still in the released state, when the concentration reaches a certain value, It will explode and cause a fire. [0003] At present, the prior art usually adopts the installation of NB smoke detectors in the kitchen to...
